Beneficial effect lies in: production simple process, the small investment, with low costs, production efficiency is high, and the technical matters is mastered very easily, the mass production of being convenient for, light guide plate light conductivity is good, and the thermal diffusivity is good to the phenomenon of light guide plate jaundice under the high temperature condition has been avoided.
Description
Technical field
This utility model belongs to light guide plate apparatus field, is specifically related to a kind of LED light light guide plate.
Background technology
Light guide plate is with optical grade acrylic as base material, uses LED display and the backlight mould of notebook computer
Group technology, through the overall height light transmittance of light guiding points, makes light guide plate light be converted to light guiding points design through computer
The equal light state of area source manufactures molding.Product uses spectrophotometry and pulse laser engraving technology,
V-Cutting ruling combines and at constant temperature, constant humidity, dustless in the environment of be made, have ultra-thin
Brightness, guide-lighting uniform, energy-conserving and environment-protective, no dark space lamp distinguishing feature.LED is a point source, and it must be
Repeated reflection in light guide plate, when light occurs reflection when, will expand from convex site by some light
Shed, then penetrate screen illuminating from surface, it is therefore necessary to light guide plate is made sufficiently thin, so could obtain
To higher brightness.The LED light guide plate that industry is the thinnest at present is at about 0.8mm, to thinner, reflection
The demand of efficiency more preferably light guide plate is more and more urgent, but current process technology is not met by requirement, and
And the light guide plate the currently used shortcomings such as to there is thermal diffusivity poor, and cost of investment is high.
Utility model content
The purpose of this utility model is that provides a kind of LED light light guide plate to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of LED light light guide plate, including heat radiation pore, LED lamp bead, dark slide and protecting film, carriage
It is provided with heat radiation pore on frame lower surface, the inner surface of support frame one side arranges LED lamp bead, the most right
LED lamp bead and be internally provided with light guide plate main body in support frame, is provided with reflector plate below light guide plate main body,
Light guide plate main body is provided above diffusion sheet, and diffusion sheet is provided above brightening piece.
In said structure, the light source that LED lamp bead produces is passed by light guide plate main body, and a part of light source leads to
Crossing reflector plate and be reflected back light guide plate main body, thus decrease loss of light source, light source passes through diffusion sheet diffusion,
Hence into brightening piece, further enhance illumination, irradiate out eventually through protecting film.
As preferred version of the present utility model, light guide plate main body is connected by bonding with diffusion sheet, diffusion
Sheet is connected by bonding with brightening piece.
As preferred version of the present utility model, brightening piece is connected by bonding with protecting film, protecting film with
Dark slide is connected by screw.
Having the beneficial effects that: production technology is simple, small investment, low cost, production efficiency is high, technical matters
It is very easy to grasp, it is simple to producing in enormous quantities, light guide plate light conductive performance is good, and thermal diffusivity is good, thus
Avoid the phenomenon of light guide plate jaundice under hot conditions.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of LED light light guide plate described in the utility model.
Description of reference numerals is as follows:
1, support frame；2, heat radiation pore；3, LED lamp bead；4, dark slide；5, protecting film；6, increase
Mating plate；7, diffusion sheet；8, light guide plate main body；9, reflector plate.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And embodiment, this utility model is further elaborated.Should be appreciated that described herein specifically
Embodiment, only in order to explain this utility model, is not used to limit this utility model.
As it is shown in figure 1, a kind of LED light light guide plate, including heat radiation pore 2, LED lamp bead 3, dark slide
4 and protecting film 5, support frame 1 lower surface is provided with heat radiation pore 2, reaches the purpose of heat radiation, thus
Prevent various components inside by high temperature failure, the inner surface of support frame 1 one side arrange LED lamp bead 3,
Just it is internally provided with light guide plate main body 8 to LED lamp bead 3 and in support frame 1, sets below light guide plate main body 8
Being equipped with reflector plate 9, light guide plate main body 8 is provided above diffusion sheet 7, and diffusion sheet 7 is provided above brightening piece
6, brightening piece 6 is provided above protecting film 5, it is possible to play the effect of being effectively protected, and prevents internal part quilt
Scratching, or destroyed by external force, protecting film 5 lateral symmetry is provided with dark slide 4, and dark slide 4 can play
Prevent the effect that light source scatters and disappears.
In said structure, the light source that LED lamp bead 3 produces is passed by light guide plate main body 8, a part of light
Source is reflected back light guide plate main body 8 by reflector plate 9, thus decreases loss of light source, and light source passes through diffusion sheet 7
Diffusion, hence into brightening piece 6, further enhances illumination, irradiates out eventually through protecting film 5.
As preferred version of the present utility model, heat radiation pore 2 is by punching press on support frame 1 lower surface
Forming, LED lamp bead 3 is connected by screw with support frame 1, and LED lamp bead 3 and light guide plate main body 8 exist
Article one, on horizontal linear, light guide plate main body 8 and reflector plate 9 is connected by bonding, light guide plate main body 8 with
Diffusion sheet 7 is connected by bonding, and diffusion sheet 7 is connected by bonding with brightening piece 6, brightening piece 6 and
Protecting film 5 is connected by bonding, and protecting film 5 is connected by screw with dark slide 4.
Of the present utility model ultimate principle, principal character and advantage have more than been shown and described.The skill of the industry
Art personnel are it should be appreciated that this utility model is not restricted to the described embodiments, in above-described embodiment and description
Describe simply illustrates principle of the present utility model, on the premise of without departing from this utility model spirit and scope,
This utility model also has various changes and modifications, and these changes and improvements both fall within this claimed practicality
